thank you i will improve on these

 I didnt like the rock shadows :S

 I'm having a hard time finding out what this even is. What I assume are rocks are a bit more"bulbish" than they should be. Try making some cracks here and there, eh?

thank you for the criticism

 That's too much dithering to my eyes, also what's with the bright green? Is it grass or moss on the rocks? If so, it could be more detailled and use a better palette :)
